Frequently Asked Questions
Q: What happens if my pH is too high?
A: High pH can cause cloudy water, scale buildup, reduced sanitizer effectiveness and swimmer discomfort.
Q: How often should I use pH Minus?
A: Use as needed after testing, especially following shocking, heavy use or rainstorms that may raise pH.
Q: Will this product affect chlorine levels?
A: It won’t reduce chlorine levels directly, but it improves chlorine efficiency by restoring the proper pH range.
Q: Is this product safe for saltwater pools?
A: Yes. It is compatible with all types of pools and sanitation systems.
Q: Can I use this product to lower total alkalinity as well as pH?
A: Yes. Poolife™ pH Minus lowers both pH and total alkalinity, especially when added in small increments and applied in a concentrated area with the pump off briefly to target alkalinity more directly.
Q: Should I dilute Poolife™ pH Minus before adding it to the pool?
A: While dilution is not always required, it’s a good idea to pre-dissolve in a bucket of water if adding near sensitive surfaces or if you want to avoid granules settling at the bottom.
Q: How long should I wait before retesting after adding this product?
A: Allow the water to circulate for at least 4–6 hours before retesting and making further adjustments.
Q: Can I swim after using pH Minus?
A: Yes — once the product is fully dissolved and the water has circulated, swimming is safe. Always ensure pH has returned to the ideal 7.2–7.6 range before use.
